MY SON IS 23 YEARS OLD,6'2", AND ABOUT 220 LBS. HE IS HAVING PAIN IN HIS KIDNEYS. SONOGRAM SHOWED NO ABNORMALITY IN KIDNEYS. SPLEEN WAS SLIGHTLY ENLARGED. HE IS FEELING NAUSEATED AND HAS VOMITED TWICE IN 24 HRS. Dr. SAYS CREATININE LEVEL IS 3. PAIN IS ALSO IN LOWER ABDOMEN REGION. HE HAS A GREAT THIRST AND IS DRINKING A LOT. AT THIS TIME HE IS IN THE HOSPITAL WITH AN IV FOR FLUIDS. SUGAR LEVEL IS FINE. ANY IDEAS ON WHAT THIS COULD BE OR WHAT QUESTIONS I SHOULD BE ASKING? IS THERE SOMETHING I MIGHT SUGGEST FOR THE DOCTOR TO INVESTIGATE?
